eli5 How can PC games from literally 1998 run from the PCs of today but you can’t play older console games from the current consoles?

Question

why is “backwards incompatibility” a problem on consoles and not on pc when they’re basically just the same electronic parts (cpu, gpu, ram)

Answer 1

The new computers are all capable of running the games if there was software to do it. Companies just don’t want to spend money on that software.
